Higher Education of Single and Married Mothers

This paper describes an Australian sample of 78 single and 107 partnered mothers who entered or re‐entered tertiary study as mature age students. 27% were early school leavers; of those who had matriculated, early marriage and/or early pregnancy were major reasons for non‐continuance with study, and this was particularly the case among those who subsequently became single mothers. Both partnered and single were enrolled in more traditionally female courses of study than were younger female students attending the same institutions. Some four‐fifths of the sample felt they were managing their time, work, relationships, finances and overall coping poorly or very poorly. However their academic performance was well above average. The single mothers felt they were coping rather better than the married, especially with regard to money (despite being poorer), relationships and time. Overall satisfaction with university life was very high, with the main benefits reported by both single and partnered mothers being self‐esteem, knowledge, intellectual interests and intelligence. Career benefits and financial potential were mentioned less often as main benefits and only slightly more frequently by the single mothers. The question is raised of whether mature age women students, as well as female school leavers, should be encouraged to enter non‐traditional courses of study.     

The Use of Reflective Journals in Initial Teacher Training

The intention of this article is to examine the role of reflective journals in Initial Teacher Training courses, and, in particular, how they can enable students to develop critical independence for professional self-appraisal. It explores the value of journal writing in the process of learning about teaching by reproducing an edited extract of one PGCE (Post-Graduate Certificate in Education) student's course journal, and by offering both a student's and a tutor's perspective of the significance of the journal.     

Effects of sequences of sucrose reward magnitudes with short ITIs in rats

Two experiments assessed the role of aftereffect learning in rats rewarded with sucrose solutions. In Experiment 1, rats were trained in a single straight runway for two trials on each of 18 days, each trial terminating with either large (20% scurose) or small (3% sucrose) reward. The ITI was 3–5 min. The sequence of daily rewards for each of four groups was small-small (SS), small-large, (SL), large-small (LS), or large-large (LL). Response patterning and a simultaneous negative contrast effect were observed in LS and SL relative to the consistently rewarded controls. During 10 massed extinction trials, resistance to extinction was greatest for Group SL, followed in order by Groups SS, LL, and LS. Experiment 2 examined single alternation of large and small rewards administered for 10 trials on each of 31 days with an ITI of 60 sec. Reward for one group was 20% or 3% sucrose while another received 1 or 10 45-mg Noyes pellets. Appropriate patterning developed only in the food-pellet rewarded animals. The overall results suggest that sucrose rewards may produce high-amplitude and long-duration aftereffects which interfere with learning in designs employing several massed daily trials, but which may facilitate learning—relative to food-pellet rewards—with longer intertrial intervals and fewer daily trials.     

Fractions as the Coordination of Multiplicatively Related Quantities: A Cross-Sectional Study of Children's Thinking

Although equal sharing problems appear to support the development of fractions as multiplicative structures, very little work has examined how children's informal solutions reflect this possibility. The primary goal of this study was to analyze children's coordination of two quantities (number of people sharing and number of things being shared) in their solutions to equal sharing problems and to see to what extent this coordination was multiplicative. A secondary goal was to document children's solutions for equal sharing problems in which the quantities had a common factor (other than 1). Data consisted of problem-solving interviews with students in 1st, 3rd, 4th, and 5th grades (n=112). We found two major categories of strategies: (a) Parts Quantities strategies and (b) Ratio Quantities strategies. Parts quantities involved children's partitions of continuous units expressed in terms of the number of pieces that would be created. Ratio quantities involved children's creation of associated sets of discrete quantities. Within these strategies, children drew upon a range of relationships among fractions, ratio, multiplication, and division to mentally or physically manipulate quantities of sharers and things to produce exhaustive and equal partitions of the items. Additionally, we observed that problems that included number combinations with common factors elicited a wider range of whole-number knowledge and operations in children's strategies and therefore appeared to support richer interconnections than problems with relatively prime or more basic number combinations.     

Ordinal position in the serial learning of rats

Rats were runway trained on each of two, three-trial series consisting of different varieties of reward (X, Y, and Z) and nonreward (N) serving as trial outcomes. The two series are represented as XNY and ZNN. Distinguishing the two series were different brightness and texture cues on the runway floor. Transfer tests, conducted after the rats had developed faster running for rewarded trials than for nonrewarded trials and slower running on Trial 2 of ZNN than on Trial 2 of XNY, provided evidence that trial position, rather than item memories, was controlling the discriminations. In Experiment 1, reversing the floor cues completely reversed the discriminations. In Experiment 2, transfer to NNN did not change the routine patterns of approach that had been established.
